@Marcel Drechsler and
@Xavier STROTTNER just posted their latest discovery: Strottner-Drechsler 155 (
https://www.astrobin.com/vy1kma/), so when the sky cleared and the moon was rather low last night I thought I would check if my dual-RASA8 rig could detect it. My SQM is usually above 21 but snow on the ground lightens up the sky so the meter showed 20.5. The object was also very low so I could only collect 2 x 2.25 hours before it fell below the horizon. Still, I could catch the S-D 155 together with the Cone Nebula and Dreyer's nebula (IC447).
S-D 155 is the blue object near the lower right corner. With only 4.5 hours and a focal length of 400 mm it is of course not as outstanding as it is in their 80 hours 1200 mm image, but there it is, and I think it is nice to see it in a wider context.
